One other difference between the frame on this gun and the 1970's Mauser frame is the width of the boarder around the frame ears left after milling. It's narrow on the 1970's Mauser frame, and the one shown is wider as in an Imperial era Luger frame.
Again, I don't know if the later Mauser Parabellum production made closer to what Sam Cummings wanted changed back to the wider ear border.
I'm trying to visualize the "fingers" on the rear of the frame.
This is the rear of my M1906 DWM luger:
This is a later P08 Luger:
Are these areas around the notch the "fingers" mentioned?
